Abstract
Provided is a hydrogen separation filter allowing a hydrogen purification at a lower temperature than conventional one, and a method for manufacturing the same. A hydrogen separation filter includes a porous substrate, a lattice expansion layer formed on the porous substrate and containing a first material, and a hydrogen dissociation and transmission layer formed on the lattice expansion layer and containing a second material selected from the group consisting of Pd, V, Ta, Ti, Nb, and alloys thereof. The first material and the second material have a same crystalline structure. A lattice constant aof a first bulk material having a same composition and a same crystalline structure as the first material and a lattice constant aof a second bulk material having a same composition and a same crystalline structure as the second material satisfy a formula (1):1.03≤1.15 (1).
